Can an ileoproctostomy be performed after a subtotal colectomy with ileostomy placement has already been done?

Ileoproctostomy: Ileoproctostomy can be done after ileostomy provided the particular patieint is a candidate for the takedown and anastomosis of the ileum and the rectum.

Yes: After removal of all colon to the peritoneal reflection or just below, there is a stump of distal bowel that remains. In many cases the surgeon can anastomosis proximal bowel to the anal stump at the levators . (the muscles of the rectal sphincter). If an exiting ileostomy is present, a pouch can be formed and anastomosed to the region just above rectum.
